I am 9 months post op and have this same problem. Great question for the old guys to see if this does get better with time. I really hope so. I too have less leaking with Viagra but still some just the same. I missed participtaing in another other aspect of our sexual relationship ( you know) so we tried flavored condoms and that seems to be an acceptable alternative until I can get the faucet fixed.
Also I use a restrictor ring as well and that does help. So with Viagra and the ring and a towel and all the other prep stuff we are able to have a good relationship and for that I am very thankful. I have been married for 37 years so we are old pro's, I sympathise with the brothers who have a new or multiple partners.
